Cellular infrastructure and the internet enables what we have today. A smartphone is a convenience.
Right now a smartphone is a "convenience" in the same way that the internet was a convenience less than 10 years ago, and there have already emerged entire industries where it is a necessity to have a working smartphone (for example, being a rideshare driver).
Citation needed. Calls are still a thing. And cellular infrastructure enables all of that.
Yes, calls are a thing. Paper maps and single-purpose GPS units are also a thing. That doesn't change the fact that road navigation is now being done overwhelmingly more via smartphone than those other two methods combined in most parts of the developed world. It is a very wide grey line between "convenience" and "deeply ingrained part of society", to be sure, but smartphones are far closer to latter than the former.
Smartphones are a form factor.
It is the most ubiquitous form factor on the face of the Earth. So ubiquitous, in fact, that there are few (if any) places in the world where the other cellular "form factors" are seen by the vast, vast majority of people as an anachronism.
It is so ubiquitous that you could choose
any city in the world that has
any kind of cell service, interact with 200 adults in that city, and at least 190 of them will have a smartphone on their person at the moment you interact with them. You could do the same thing with 200 children over the age of, say, ten years old, and you'd still find at least 100 carrying a smartphone.
There are more people who own a smartphone than own a car today. That wasn't the case less than 10 years ago.
All of the above can be done on other form factors that have access to the internet.
Sure. I can also call a cab on my landline telephone to drive me to a department store to buy a DVD to watch this evening. All of those things actually still exist. That doesn't change the fact that most of the world would do none of the above. Those things still exist, but that also doesn't mean that those things aren't going to disappear sometime very soon because of the technologies that are quickly replacing them.
Just as my smartphone already replaced my physical RSA fob. Nearly ten years ago.
In real life, I do my banking on my pc
As do I, because I prefer it. My wife, on the other hand, who does most of the banking, does it on her smartphone.
Without smartphone or token-based MFA? Brave.
make calls in my cell phone.
Your cell phone being what form factor exactly? Now be honest.
Your theoretical argument holds no water. You are attempting to elevate a smartphone to the level of air, food and water.💧
And you are trying to demote it to a mere toy. That, and you apparently also want to pretend that human society can exist with merely air, food, and water and no infrastructure. Good luck with that.
All you really have to do is look at the evolution of the internet from a mere curiosity (early 2000's) to a mere convenience (late 2000's or even early 2010's for some people) to an absolute necessity (definitely any time after 2020, probably much earlier than that for many people) and see how the evolution of smartphones are following that same trajectory. On that same timeline, I would say that smartphones are about where the internet was on the "convenience/necessity" scale of the internet in about 2015. Maybe a bit later than that.
Btw I plan my trips on google maps on my desktop or my tesla screen. No smartphone needed.
You want to throw around "form factor" as an argument, and then say that you basically do all your mapping on what amounts to a giant smartphone on wheels. And then you want to try to convince people that you use Google maps exclusively on your desktop computer to "plan" your trips, and that you never open the mapping app in the smartphone you carry in your pocket everyday.
Yeah, OK bud.
